Description

  The present invention relates to a label producing apparatus for producing a printed label using a label producing tape.

  2. Description of the Related Art Conventionally, a label producing apparatus that produces a print label using a label producing tape is known. In this label producing apparatus, when a tape cartridge is loaded in the cartridge holder, the label producing tape is fed out from the tape roll stored in the cartridge by the conveying means, and desired printing is performed by the printing means. Created.

  In the structure in which the tape is fed out from the tape roll as described above, a technique for detecting the tape remaining amount by detecting the angular velocity of the tape roll is known (for example, see Patent Document 1). This prior art utilizes the fact that the tape roll rotates faster when the remaining tape amount in the tape roll decreases. That is, the rotary encoder provided on the tape roll is detected by an optical sensor, and the angular velocity of the tape roll is detected from the pulse output. When this angular velocity reaches a preset angular velocity, the remaining tape amount is notified.

JP 2001-278517 A

  The label producing apparatus described above includes, for example, a so-called laminate-type print label that is produced by bonding a printed cover film to a label producing tape, or a so-called non-print produced by directly printing on a label producing tape. There are some which can create a plurality of types of print labels such as laminate type print labels. In such a label producing apparatus, different types of tape cartridges are used depending on the type of print label to be produced. Generally, when the types of tape cartridges are different, the tape thickness of the label forming tape stored in the cartridge, the inner peripheral diameter of the tape roll, and the like are also different.

  Here, when the angular velocity of the tape roll is detected and the remaining tape amount is calculated from the angular velocity as in the above prior art, it is not clearly described in Patent Document 1, but the tape thickness and the tape roll Parameters such as circumference are required. Therefore, when the above prior art is applied to the label producing apparatus in order to detect the remaining tape amount in the tape roll in the label producing apparatus described above, the tape thickness and the inner peripheral diameter of the tape roll depend on the type of the tape cartridge as described above. Since the parameters such as the above change, there is a possibility that the remaining amount of the tape cannot be accurately detected.

  An object of the present invention is to provide a label producing apparatus that allows an operator to reliably recognize the remaining amount of tape even when producing a plurality of different types of printed labels.

In order to achieve the above object, a label producing apparatus according to a first aspect of the present invention is configured to be detachable from an apparatus casing constituting an outline of the apparatus and a tape roll wound with a label producing tape. A roll holder provided; type information acquisition means for acquiring type information of the tape roll mounted on the roll holder; and the tape roll mounted on the roll holder on the tape roll side or the apparatus housing side. A plurality of detectors formed at predetermined intervals in the circumferential direction of the detection target provided to rotate at an angular velocity linked to the angular velocity are acquired by an optical detection means for optically detecting the detection information and the type information acquisition means. Based on the type information and the detection result of the optical detection means, the remaining amount specifying means for specifying the tape remaining amount of the tape roll, and the tape specified by the remaining amount specifying means Possess the remaining related information outputting means for outputting the remaining related information related to the amount on the display means, the said roll holder has been detachably mounted in the tape cartridge containing the tape roll in the cartridge housing A cartridge holder, wherein the type information acquisition unit acquires type information of the tape cartridge mounted on the cartridge holder, and the optical detection unit is installed in a cartridge housing of the tape cartridge mounted on the cartridge holder. The plurality of detectors formed on the detection object provided to rotate at the same angular velocity as the tape roll are optically detected from the outside of the cartridge housing .

  When the tape roll is mounted on the roll holder of the label producing apparatus, the label producing tape is fed out from the tape roll by the conveying means of the label producing apparatus, and at the same time the label producing tape or the print-receiving tape bonded to the tape by the printing means Desired printing is performed, and a printed label is created. At this time, the tape roll is rotated around the spool, and the label producing tape is fed out. However, since the outer diameter of the tape roll gradually decreases as the label producing tape is fed out, the tape transport speed is constant. In this case, the angular velocity around the spool of the tape roll gradually increases according to the roll outer diameter. As described above, there is a predetermined correlation between the roll outer peripheral diameter (that is, the remaining tape amount) and the angular velocity of the tape roll, and it is possible to specify the remaining tape amount from the angular velocity of the tape roll using this correlation. .

  Here, in the label producing apparatus, for example, a so-called laminate type print label that is produced by pasting a printed tape to be printed on a label producing tape, or by directly printing on a label producing tape. It is possible to create a plurality of different types of print labels such as so-called non-laminate type print labels. In this case, a plurality of different types of tape rolls are used depending on the type of print label to be created. When the type of tape roll is different, the correlation between the remaining tape amount and the angular velocity of the tape roll is also different.

In the first invention of this application, the type information acquiring means acquires the type information of the tape roll mounted on the roll holder. In addition, a detected body that rotates at an angular velocity interlocked with the angular velocity of the tape roll is provided on the tape roll side or the apparatus housing side, and the optical detection means optically detects the detector of the detected object. Then, the remaining amount specifying unit specifies the tape remaining amount of the tape roll on the basis of the type information acquired by the type information acquiring unit and the detection result of the optical detecting unit, and the remaining amount related information output unit outputs the specified tape remaining amount. The remaining amount related information related to the quantity is output to the display means. Accordingly, the remaining amount related information can be displayed on a display unit such as a liquid crystal screen of the label producing apparatus itself or a display unit of a PC terminal connected to the label producing apparatus via a network or the like as a display unit. it can.

As described above, the tape roll is specified based on the type information of the tape roll and the detection result of the optical detection means, so that the tape roll can be used even when the plurality of different types of tape rolls described above are used in the label producing apparatus. The remaining amount of tape can be specified corresponding to the type of the tape. As a result, the operator can reliably recognize the remaining amount of tape even when creating a plurality of different types of print labels. Also, it is possible to install the cartridge containing the tape roll in the cartridge holder and supply the label creation tape from the cartridge to create the print label, as above, corresponding to the tape roll type (cartridge type). It is possible to reliably specify the remaining tape amount.

  The label producing apparatus according to a second aspect of the present invention includes a first storage unit that stores a remaining amount table that represents a correlation between an angular velocity of the tape roll and a remaining tape amount for each type of the tape roll in the first invention, The remaining amount identifying unit refers to the correlation corresponding to the type information acquired by the type information acquiring unit in the remaining amount table, and corresponds to the angular velocity of the tape roll based on the detection result of the optical detecting unit. The tape remaining amount of the tape roll is specified by extracting the tape remaining amount.

  In the second invention of the present application, a remaining amount table that represents the correlation between the tape roll angular velocity and the tape remaining amount for each type of tape roll is stored in advance in the first storage means. Then, the remaining amount identifying means refers to the correlation corresponding to the type information in the remaining amount table, and extracts the remaining tape amount corresponding to the angular velocity of the tape roll based on the detection result of the optical detecting means. Identify the remaining tape.

  In this way, by specifying the remaining tape amount using the remaining amount table prepared in advance, the calculation becomes unnecessary as compared with the case where the remaining tape amount is sequentially calculated based on the detection result of the optical detection means. The control contents related to the remaining amount detection can be simplified. As a result, the CPU and the like can be made low specification and cost can be reduced. In addition, there is an effect that the time required for specifying the remaining amount of tape can be shortened by the amount that calculation is not required.

  According to a third aspect of the present invention, there is provided the label producing apparatus according to the first aspect, further comprising parameter information acquisition means for acquiring parameter information relating to the tape roll based on the type information acquired by the type information acquisition means, The specifying unit calculates the remaining tape amount based on a predetermined calculation formula using the parameter information acquired by the parameter information acquiring unit and the angular velocity of the tape roll based on the detection result of the optical detection unit. Thus, the tape remaining amount of the tape roll is specified.

  In the third invention of the present application, the parameter acquisition unit acquires the parameter information related to the tape roll based on the tape roll type information acquired by the type information acquisition unit. Then, the remaining amount specifying unit calculates the remaining tape amount based on a predetermined calculation formula using the parameter information acquired by the parameter information acquiring unit and the angular velocity of the tape roll based on the detection result of the optical detection unit. .

  In this way, by sequentially calculating the remaining amount of tape based on the parameter information and the detection result of the optical detection means, the amount of data in the table can be compared with the case where the remaining amount of tape is specified using a table prepared in advance. Therefore, the remaining amount of tape can be detected with high accuracy without being affected by accuracy. As a result, the operator can grasp the tape remaining amount in detail. In addition, because the remaining amount of tape can be detected with high accuracy, print labels are continuously created according to the remaining amount of tape, and the conveying force (tape feeding force) by the conveying means is controlled according to the remaining amount of tape. It is possible to perform processing using the remaining amount of tape, such as stabilization of tape conveyance.

  According to a fourth aspect of the present invention, there is provided the label producing apparatus according to the third aspect, further comprising: a second storage unit that stores a parameter table representing the tape thickness of the label producing tape and the inner circumference of the tape roll for each type of the tape roll The parameter information acquisition means acquires the tape thickness of the tape for label production and the inner diameter of the tape roll corresponding to the type information as the parameter information by referring to the parameter table, The remaining amount specifying means is based on a predetermined calculation formula using the tape thickness and the inner peripheral diameter of the tape roll obtained by the parameter information obtaining means and the angular velocity of the tape roll. The tape remaining amount is calculated to identify the tape remaining amount of the tape roll.

  In general, parameter information such as the tape thickness of the label producing tape and the inner diameter of the tape roll may be different when the type of the tape roll is different. Therefore, in the fourth invention of the present application, a parameter table representing the tape thickness of the label producing tape and the inner peripheral diameter of the tape roll for each type of tape roll is stored in advance in the second storage means. Then, the parameter information acquisition unit refers to the parameter table, and acquires the tape thickness and the inner peripheral diameter of the tape roll corresponding to the tape roll type information acquired by the type information acquisition unit as parameter information. Then, the remaining amount specifying means calculates the remaining tape amount using the parameter information and the angular velocity of the tape roll.

Thus, as the parameter information, the tape remaining amount corresponding to the tape roll type is reliably obtained by obtaining the tape thickness and inner diameter of the tape roll that are different for each tape roll type and calculating the tape remaining amount. Can be identified.
Further, by specifying the tape thickness and the inner diameter of the tape roll using the parameter table prepared in advance as described above, the type information acquisition means adds the tape thickness and the inner circumference of the tape roll in addition to the tape roll type information. Since the amount of information to be acquired can be reduced as compared with the case of acquiring the diameter, for example, when the type information acquisition means is a mechanical sensor mechanism, the structure of the sensor mechanism can be simplified.

According to a fifth aspect of the present invention, there is provided the label producing apparatus according to the fourth aspect, further comprising conveying means for conveying the label producing tape fed from the tape roll at a conveying speed S (mm / s), and the remaining amount identifying means is The tape roll thickness t (mm) acquired by the parameter information acquisition means and the inner peripheral diameter d (mm) of the tape roll and the angular velocity ω of the tape roll based on the detection result of the optical detection means. (Rad / s) is used to calculate the tape remaining amount M based on the formulas 1 and 2 as the predetermined calculation formula.
M = π (D ² −d ² ) / 4t (Formula 1)
D = 2S / ω (Formula 2)

  When the types of tape rolls are different, parameter information such as the tape thickness t of the label producing tape and the inner peripheral diameter d of the tape roll may be different. As the parameter information, the tape remaining amount M corresponding to the tape roll type is obtained by obtaining the tape thickness t and the inner peripheral diameter d of the tape roll that are different for each tape roll type and calculating the remaining tape amount M. Certainly can be identified.

  According to the present invention, even when a plurality of different types of print labels are created, the operator can reliably recognize the remaining tape amount.

The tape is fed in the direction indicated by the arrow T in FIG. That is, the tape feed roller 18 also functions as a tape pressure roller.

  The ribbon take-up roller 15 and the tape feed roller 18 are driven by a driving force of a tape feed motor 33 (see FIG. 8 described later) provided outside the cartridge 10 via a gear mechanism (not shown). By being transmitted to the ribbon take-up roller drive shaft 31 and the tape feed roller drive shaft 30, they are driven to rotate in conjunction with each other.

  Further, the cartridge 10 has a detected portion 24 at a corner opposite to the tape feeding roller 18 (upper right corner in FIG. 3). The detected portion 24 is provided with a plurality of switch holes in a predetermined pattern. As described above, each pattern includes the type of the cartridge 10, the tape thickness of the base tape 16, and the base material. The cartridge type information including the inner peripheral diameter of the tape roll 17 and the like is included. The above-described cartridge sensor 37 (see FIG. 2) detects different switch hole patterns depending on the type of each cartridge 10 as described above, and thereby detects the type of cartridge 10 (in other words, the type of roll). Can do.

  On the other hand, the cartridge holder 27 has the print head 19, the ribbon take-up roller drive shaft 31, the tape feed roller drive shaft 30, and the roller holder 22. The print head 19 includes a large number of heating elements, and performs printing on a predetermined print area of the cover film 11 fed out from the cover film roll 12.

  The tape feed roller drive shaft 30 is configured so that the cover film 11 fed from the cover film roll 12 of the cartridge 10 mounted on the cartridge holder 27 and the base tape 16 fed from the base tape roll 17 are transferred to the tape feed roller 18. It is conveyed by driving. That is, the tape feed roller drive shaft 30 corresponds to a transport unit.

  The roller holder 22 is pivotally supported by a support shaft 29 and can be switched between a printing position and a release position by a switching mechanism.

When the roller holder 22 is switched to the printing position, the platen roller 20 and the tape pressure roller 21 are The print head 19 and the tape feed roller 18 are pressed against each other.

  Further, a cutter 28 is disposed in the cartridge holder 27 adjacent to the discharge port (not shown) of the cartridge 10. The cutter 28 is activated when a cutter driving button 38 (see FIG. 8 described later) is pressed, and the printed label tape 23 is cut into a predetermined length to generate a printed label LB1.

  Further, the base tape spool 17a has axial bases (perpendicular to the paper surface in FIG. 3) at both ends so as to contact both ends of the base tape roll 17 in the width direction (perpendicular to the paper surface in FIG. 3). Ring-shaped film members 73 and 74 are provided for preventing problems due to the sticking out of the adhesive of the material tape 16. Among these, the film member 74 (see FIG. 3) on the lower side when the cartridge 10 is mounted on the cartridge holder 27 has a light-reflective region 75w and a light-absorbing region at the outer peripheral side end in the radial direction. A plurality of detectors 75 constituted by 75 b are formed at predetermined intervals in the circumferential direction of the base tape roll 17. As shown in the figure, 48 detectors 75 are formed in this embodiment, but other numbers may be used. For example, the outer peripheral surface of the base tape spool 17a is rotated such that the film member 74 rotates at an angular velocity (in this example, the same angular velocity) linked to the base tape roll 17 (specifically, the base tape spool 17a). It is provided to engage with. In this specification, the film member 74 is appropriately referred to as a “detected body 74”.

  The detection object 74 is made of a transparent or translucent film material. The light reflective region 75w constituting the detector 75 is formed by printing white or silver on a film and reflects incident light. The light-absorbing region 75b is formed transparent or semi-transparent by printing black on the film or by not printing or the like, and absorbs or transmits incident light.

  The film member 73 (see FIG. 2), which is on the upper side when the cartridge 10 is mounted on the cartridge holder 27, is made of a transparent or translucent film material, like the film member 74. Thereby, as shown in FIG. 2, the operator can visually check the remaining tape amount through the film member 73 in the remaining amount confirmation window 71.

  The detector 75 has a radially outer end on the detected body 74, more specifically, the outer circumference of the base tape roll 17 is larger than the contour of the roll when the outer diameter of the base tape roll 17 is the largest (the state shown in FIG. 3). It is formed in the region which becomes the side. Thereby, since the outer peripheral diameter of the base tape roll 17 only becomes smaller with the feeding of the base tape 16 thereafter, the detector 75 and the outline of the roll do not overlap, and the detection by the first optical sensor 51 is performed. The child 75 can be detected satisfactorily.

  Further, as described above, the detection light from the first optical sensor 51 that optically detects the detector 75 of the detection object 74 is transmitted from the outside of the cartridge housing 70 to the lower portion 70d of the cartridge housing 70. A transmission hole 72 is provided. In the present embodiment, the transmission hole 72 is formed in a circular shape.

  In the above configuration, after the cartridge 10 is mounted on the cartridge holder 27, the ribbon take-up roller drive shaft 31 and the tape feed roller drive shaft 30 are synchronized with each other by the driving force of the tape feed motor 33 (see FIG. 8 described later). Is rotated. As the tape feed roller drive shaft 30 is driven, the tape feed roller 18, the platen roller 20, and the tape pressure roller 21 rotate to feed the base tape 16 from the base tape roll 17, and the tape feed roller 18 as described above. Supplied to. On the other hand, the cover film 11 is fed out from the cover film roll 12, and a plurality of heating elements of the print head 19 are energized by a print head drive circuit 32 (see FIG. 8 described later). At this time, the ink ribbon 13 is pressed against the print head 19 to be brought into contact with the back surface of the cover film 11. As a result, desired printing is performed in a predetermined printing area on the back surface of the cover film 11. The base tape 16 and the cover film 11 after printing are bonded and integrated by a tape feeding roller 18 and a tape pressing roller 21 to form a printed label tape 23, and a cartridge is formed from the discharge port. 10 is carried out. Then, the printed label tape 23 is cut by the cutter 28, and a print label LB1 on which a desired print is made is generated.

  In addition, the said base tape 16 is corresponded to the tape for label production as described in a claim, and the said base tape roll 17 is equivalent to a tape roll. The cartridge 10 corresponds to a tape cartridge.

  With reference to FIG. 4, the structure of the peripheral portion of the cartridge holder 27 in a state in which the heat-sensitive type cartridge 10 'is mounted will be described. In FIG. 4, the same parts as those in FIG. 3 are given the same reference numerals and the description thereof is omitted, and only the parts different from FIG. 3 will be described.

  In FIG. 4, the cartridge 10 'has a thermal tape roll 17' around which a thermal tape 16 'is wound. Unlike the laminate type cartridge 10, the cartridge 10 ′ does not have a cover film roll 12 around which the cover film 11 is wound, a ribbon supply side roll 14, and a ribbon take-up roller 15. The heat-sensitive tape roll 17 'winds the heat-sensitive tape 16' around a heat-sensitive tape spool 17a 'that is rotatably fitted and accommodated in a boss 95 standing on the bottom surface of the cartridge 10'.

  In this example, the heat-sensitive tape 16 'has a three-layer structure (see a partially enlarged view in FIG. 4), and is directed from the side wound inside (left side in FIG. 4) to the opposite side (right side in FIG. 4). A cover film 16a 'made of PET (polyethylene terephthalate) having a heat-sensitive recording layer on the surface, an adhesive layer 16b' made of an appropriate adhesive material, and a release paper 16c 'are laminated in this order.

  When the cartridge 10 'is mounted on the cartridge holder 27 and the roller holder 25 is moved from the separation position to the contact position, the thermal tape 16' is sandwiched between the print head 19 and the platen roller 20, and the tape feed It is sandwiched between the roller 18 and the tape pressure roller 21. Then, the tape feed roller 18, the tape pressure roller 21, and the platen roller 20 rotate in synchronization, and the thermal tape 16 'is fed out from the thermal tape roll 17'.

  The drawn thermal tape 16 'is guided by a substantially cylindrical reel 92 that is rotatably inserted into a reel boss 91 provided upright on the bottom surface of the cartridge, while printing on the downstream side in the transport direction from the head insertion opening 39. It is supplied to the head 19. A plurality of heating elements of the print head 19 are energized by the print head drive circuit 32 (see FIG. 8 to be described later), whereby the print R is printed on the surface of the cover film 16a ′ of the thermal tape 16 ′ and printed. After being formed as a label tape 23 ', it is carried out of the cartridge 10'. Thereafter, the sheet is cut by the cutter 28, and a print label LB1 on which desired printing is performed is generated.

  The thermal tape 16 'corresponds to the label producing tape described in the claims, and the thermal tape roll 17' corresponds to the tape roll. Further, the cartridge 10 'corresponds to a tape cartridge.

  In the above, a thermal tape is used as the label forming tape, and printing is performed only by heat generation of the print head 19 without using an ink ribbon or the like. However, printing is performed using a normal ink ribbon. May be.

  The structure of the peripheral portion of the cartridge holder 27 in a state where such a receptor type cartridge 10 "is mounted will be described with reference to Fig. 5. In Fig. 5, the same portions as those in Figs. Are denoted by the same reference numerals and the description thereof is omitted, and only portions different from those in FIGS. 3 and 4 are described.

  In FIG. 5, a cartridge 10 ″ has a receptor tape roll 17 ″ around which a receptor tape 16 ″ is wound. Unlike the heat-sensitive type cartridge 10 ′, the cartridge 10 ″ is a ribbon supply side roll 14. And the ribbon take-up roller 15, but the cover film roll 12 around which the cover film 11 is wound is not provided. The receptor tape roll 17 ″ is wound around the receptor tape spool 16 ″ around a receptor tape spool 17a ″ that is rotatably fitted in a boss 95 standing on the bottom surface of the cartridge 10 ″.

  In this example, the receptor tape 16 ″ has a three-layer structure (see a partially enlarged view in FIG. 5), and is directed from the side wound inside (left side in FIG. 5) to the opposite side (right side in FIG. 5). A colored base film 16a ″ made of PET (polyethylene terephthalate), an adhesive layer 16b ″ made of an appropriate adhesive, and a release paper 16c ″ are laminated in this order.

  When the cartridge 10 ″ is mounted on the cartridge holder 27 and the roller holder 22 is moved from the separation position to the contact position, the receptor tape 16 ″ and the ink ribbon 13 are held between the print head 19 and the platen roller 20. At the same time, it is held between the tape feed roller 18 and the tape pressure roller 21. Then, the tape feed roller 18, the tape pressure roller 21, and the platen roller 20 rotate in synchronization, and the receptor tape 16 "is fed out from the receptor tape roll 17".

  On the other hand, at this time, a plurality of heating elements of the print head 19 are energized by the print head drive circuit 32 (see FIG. 8 described later), and the print R is printed on the surface of the base film 16a ″ of the receptor tape 16 ″. After being formed as the tape for tape 23 ″, it is carried out of the cartridge 10 ″. Thereafter, the sheet is cut by the cutter 28, and a print label LB1 on which desired printing is performed is generated.

  The receptor tape 16 ″ corresponds to the label producing tape described in the claims, and the receptor tape roll 17 ″ corresponds to the tape roll. The cartridge 10 ″ corresponds to a tape cartridge.

  The overall structure of the above-described sensor support mechanism 60 will be described with reference to FIG. 6A shows a state in which the cartridge 10 or the like is not attached to the cartridge holder 27, and FIG. 6B shows a state in which the cartridge 10 or the like is attached to the cartridge holder 27.

  The sensor support mechanism 60 is provided at a position facing the transmission hole 72 of the cartridge housing 70 on the bottom surface 27 b of the cartridge holder 27. The sensor support mechanism 60 includes a hollow columnar sensor support portion 61 provided so as to be exposed above the bottom surface 27 b of the cartridge holder 27 and a plate-like detection target portion provided below the bottom surface 27 b of the cartridge holder 27. 62. The sensor support portion 61 and the detected portion 62 are integrally configured.

  The sensor support portion 61 has a raised portion 63 at the upper end thereof, and the first optical sensor 51 is provided inside the raised portion 63. The outer peripheral surface of the raised portion 63 is formed in a taper shape, and is configured to be able to engage with a transmission hole 72 of the cartridge housing 70 (see FIG. 7 described later). A sensor opening 63a is formed in the upper portion of the raised portion 63, and transmits the detection light from the first optical sensor 51, which is a reflective sensor.

  Inside the sensor support 61, there is provided a spring storage chamber 65 separated from the first optical sensor 51 by a partition wall 64. The peripheral wall portion 65 a of the spring storage chamber 65 is inserted into a circular slit 27 c formed on the bottom surface 27 b of the cartridge holder 27, whereby the sensor support mechanism 60 moves the bottom surface 27 b within the spring storage chamber 65. The first optical sensor 51 is supported with respect to the bottom surface 27b of the cartridge holder 27 so as to be able to advance and retract within a possible vertical range. The spring storage chamber 65 stores a spring 66 whose upper end is in contact with the partition wall 64 and whose lower end is in contact with the bottom surface 27 b of the cartridge holder 27.

  A plurality of detection holes 67 are formed in the detected portion 62 along the axis X of the sensor support mechanism 60. Each detection hole 67 has a different opening area, and each detection hole 67 corresponds to the tape width of the cartridge 10 or the like attached to the cartridge holder 27. For example, in the example shown in FIG. 6A, the detection holes 67a, 67b, 67c, 67d, 67e, and 67f correspond to tape widths of 36 mm, 24 mm, 18 mm, 12 mm, 9 mm, and 6 mm, respectively.

  Below the sensor support mechanism 60, a second optical sensor 52 is provided by a support member 68 at a position corresponding to the axis X. The second optical sensor 52 is a transmission type having a light emitting part 52a and a light receiving part 52b (only the light receiving part 52b is shown in FIG. 6A) disposed on one side and the other side of the detected part 62, respectively. It is an optical sensor, and the detection light output from the light emitting section 52a is transmitted through the detection holes 67 in the vertical direction (perpendicular to the paper surface in FIG. 6) and input to the light receiving section 52b. As a result, the control circuit 40 (see FIG. 8 described later), which will be described later, determines which detection hole 67 faces the second optical sensor 52 based on the amount of light received by the light receiving portion 52b output from the second optical sensor 52. It can be detected. As a result, it is possible to detect the advance / retreat position of the first optical sensor 51 in a state where it contacts the cartridge housing 70 such as the cartridge 10 mounted on the cartridge holder 27.

  In the above configuration, in a state where the cartridge 10 or the like is not attached to the cartridge holder 27, the sensor support portion 61 is not pressed downward by the cartridge housing 70. Therefore, as shown in FIG. As a result, the sensor support 61 protrudes greatly upward from the bottom surface 27b of the cartridge holder 27, and the first optical sensor 51 is supported so as to be positioned relatively upward. This position is the same as the cartridge 10 having the smallest tape width among the cartridges 10 and the like that can be attached to the cartridge holder 27. In other words, even when the cartridge housing 70 having the smallest thickness is attached, the upper end of the sensor support 61 is the cartridge. The position is set such that it contacts the casing 70 and is pressed downward.

  In a state where the cartridge 10 or the like is mounted on the cartridge holder 27, the urging force of the above-described spring 66 is applied to the cartridge 10 from below by a cartridge pressing spring (not shown) provided inside the opening / closing lid 102. Even if it acts, it does not rise. As a result, in the mounted state, as shown in FIG. 6B, the sensor support 61 is pressed downward by the cartridge housing 70, and the sensor support 61 and the detected part 62 (in FIG. 6B). (Not shown) moves downward against the biasing force of the spring 66. At this time, since the cartridge housing 70 such as the cartridge 10 is formed to have a different thickness according to the tape width accommodated therein, the downward movement amount of the sensor support portion 61 and the detected portion 62 is as follows. It depends on the tape width. Therefore, the control circuit 40 (see FIG. 8 described later) detects which of the detection holes 67a to 67f is facing the second optical sensor 52, so that the tape width of the cartridge 10 or the like is increased. Can be detected. Thereafter, when the cartridge 10 or the like is removed from the cartridge holder 27, the sensor support portion 61 and the detected portion 62 are moved upward by the biasing force of the spring 66, and the state shown in FIG. At this time, the detection light of the second optical sensor 52 is blocked by a portion of the detected portion 62 where no detection hole exists. Therefore, when the amount of light received by the light receiving unit 52b is 0 (or less than a predetermined amount), it can be detected that the cartridge 10 or the like is not attached to the cartridge holder 27.

  The first optical sensor 51 corresponds to the optical detection means described in the claims.

  The structure in the vicinity of the transmission hole 72 of the cartridge housing 70 will be described with reference to FIG. 7A shows a case where the thickness of the cartridge housing 70 is different depending on each tape width. FIG. 7B and FIG. 7C show a plurality of tape widths. In this case, the cartridge housing 70 is formed to have the same thickness.

  As shown in FIG. 7A, the first optical sensor 51 has a light emitting part (not shown) and a light receiving part (not shown) arranged on the lower side of the cartridge housing 70. This is a reflection type sensor that detects the detection light output and reflected by the detection object 74 by the light receiving unit. In addition, the cartridge housing 70 has a contact portion 76 that is in contact with the first optical sensor 51 configured to be able to advance and retreat with respect to the bottom surface 27 b of the cartridge holder 27 described above around the transmission hole 72. In detail, the contact part 76 contacts the upper end part of the sensor support part 61 of the sensor support mechanism 60 mentioned above. The transmission hole 72 has a tapered portion 72 a on the inner peripheral surface that can be engaged with the outer peripheral surface of the raised portion 63 provided at the upper end portion of the sensor support portion 61. Thus, when the cartridge 10 or the like is mounted on the cartridge holder 27, the raised portion 63 provided at the upper end portion of the sensor support mechanism 60 engages with the transmission hole 72 of the cartridge housing 70, and the first optical sensor 51 The first optical sensor 51 can be positioned so that the detected light is surely transmitted through the transmission hole 72.

  When a reflective sensor such as the first optical sensor 51 is used, the distance between the sensor 51 and the detection object 74 needs to be a constant distance corresponding to the focal length L of the sensor 51. In the present embodiment, as shown in FIG. 7A, the cartridge 10 and the like are configured such that the distance between the lower surface of the cartridge housing 70 and the detected body 74 is the focal length L. The distance between the first optical sensor 51 and the detected object 74 can be held at the focal length L by bringing the portion 76 into contact with the upper end portion of the sensor support portion 61 of the sensor support mechanism 60. .

  In general, the cartridge housing 70 such as the cartridge 10 is formed to have a different thickness depending on the tape width housed therein, but the tape width is relatively small (for example, the tape width is 6 mm, 9 mm). , About 12 mm) may be formed so as to have the same thickness with respect to a plurality of tape widths due to manufacturing reasons. In this case, since the distance between the lower surface of the cartridge housing 70 and the detected body 74 varies depending on the tape width, the distance between the first optical sensor 51 and the detected body 74 is the structure shown in FIG. Does not coincide with the focal length L of the sensor 51, and the detector 75 may not be accurately detected.

  In this case, as shown in FIG. 7B and FIG. 7C, the contact portion 76 of the cartridge housing 70 formed with the same thickness but different tape width is formed on the surface of the cartridge housing 70. On the other hand, it may be configured as a stepped portion 77 that is recessed by a predetermined distance corresponding to the tape width. For example, in the example shown in FIG. 7, FIG. 7A corresponds to the tape width of 12 mm, 18 mm, and 24 mm, FIG. 7B corresponds to the tape width of 9 mm, and FIG. 7C corresponds to the tape width of 6 mm. Yes. Accordingly, in the relatively large range of the tape width such as 24 mm, 18 mm, and 12 mm, the thickness of the cartridge housing 70 is formed to be different depending on the tape width. Therefore, the structure shown in FIG. However, in a relatively small range such as 6 mm and 9 mm in tape width, a stepped portion 77 having a depth corresponding to the tape width is provided as shown in FIGS. The contact portion 76 located at the bottom is brought into contact with the upper end portion of the sensor support portion 61, whereby the distance between the first optical sensor 51 and the detected object 74 is made constant so as to be the focal length L of the sensor 51. 75 can be detected accurately.

  In the example shown in FIG. 7 described above, the stepped portion 77 is recessed by a predetermined distance from the surface of the cartridge housing 70. However, the stepped portion 77 is formed by a predetermined distance from the surface of the cartridge housing 70. The protrusion may be formed in a protruding shape so that the distance between the first optical sensor 51 and the detection object 74 is constant.

  A functional configuration of the label producing apparatus 100 will be described with reference to FIG.

  In FIG. 8, a control circuit 40 is arranged on a control board (not shown) of the label producing apparatus 100. The control circuit 40 is provided with a CPU 44, which is connected to the input / output interface 41, ROM 46, flash memory (EEPROM) 47, RAM 48, table storage unit 49, and communication interface (for communication) via the data bus 42. I / F) 43T is connected.

  The ROM 46 reads out data from a print buffer 48B, which will be described later, and prints a print drive control program for driving the print head 19 and a tape feed motor 33, which will be described later. When printing is completed, the printed label tape 23 is taped to the cutting position. Necessary for control, such as a cutting drive control program that drives and feeds the feed motor 33 and drives a solenoid 35 described later to cut the printed label tape 23, a remaining amount calculation program that calculates the remaining tape amount described later, and the like. Various programs are stored. The CPU 44 performs various calculations based on various programs stored in the ROM 46.

  The RAM 48 temporarily stores various calculation results calculated by the CPU 44. The RAM 48 is provided with a text memory 48A, a print buffer 48B, a work memory 48C for storing various calculation data, and the like. The text memory 48A stores print data such as document data.

  The table storage unit 49 is constituted by a part of the storage area of the ROM 46 or the EEPROM 47, for example. The table storage unit 49 stores the tape thicknesses of the label producing tapes 16, 16 ', 16 "as parameter information for calculating the remaining tape amount for each type of the cartridge 10 or the like (in other words, for each roll type). And a parameter table (see FIG. 13 to be described later) representing the inner peripheral diameters of the tape rolls 17, 17 ′, 17 ″. Details of the parameter table will be described later. The table storage unit 49 corresponds to the second storage unit described in the claims.

  The communication I / F 43T performs network communication with the operation terminal 400 via the communication line NW. The input / output interface 41 includes a print head drive circuit 32 for driving the print head 19, a tape feed motor drive circuit 34, a solenoid drive circuit 36, the cartridge sensor 37, a cutter drive button 38, The first optical sensor 51 and the second optical sensor 52 are connected.

  The tape feed motor drive circuit 34 drives the tape feed motor 33 to drive the tape feed roller drive shaft 30 and the ribbon take-up roller drive shaft 31 described above. The label tape 23 is conveyed. The solenoid drive circuit 36 drives a solenoid 35 that drives the cutter 28 to perform a cutting operation. The cutter driving button 38 is used by the operator to manually operate the cutter 28 so that the print label LB1 has a desired length.

  From the cartridge sensor 37, the detection result of the detected portion 24 formed in the cartridge 10 or the like described above is input, and the CPU 44 detects the type information of the cartridge 10 or the like based on the detection result. From the first optical sensor 51, a pulse which is a detection result of the detector 75 formed on the detection target 74 described above is input, and the CPU 44 detects the angular velocity of the base tape roll 17 based on the pulse period. From the second optical sensor 52, the amount of light received by the light receiving unit 52b described above is input, and the CPU 44 detects the tape width of the cartridge 10 or the like based on the amount of received light.

  In the control system centered on the control circuit 40 shown in FIG. 8, when printing data is input from the operation terminal 400 to the label producing apparatus 100 via the communication line NW, the printing data is sequentially stored in the text memory 48A. Remembered. The stored print data is read again and subjected to predetermined conversion by the conversion function of the control circuit 40, whereby dot pattern data is generated and stored in the print buffer 48B. Further, the print head 19 is driven via the print head drive circuit 32, and each of the heating elements is selectively driven to generate heat corresponding to the print dots for one line, and the dot pattern data stored in the print buffer 48B is stored. Printing is performed, and in synchronization with this, the tape feed motor 33 performs transport control of the cover film 11 and the like via the tape feed motor drive circuit 34, and finally creates a print label LB1.

  The appearance and structure of the print label LB1 produced by the label producing apparatus 100 as described above will be described with reference to FIGS. 9A, 9B, and 10. FIG.

  9A, 9B, and 10, the print label LB1 has a five-layer structure in which the cover film 11 is added to the base tape 16 shown in FIG. That is, in the order of the cover film 11, the adhesive layer 16a, the tape base layer 16b, the adhesive layer 16c, and the release paper 16d from the surface (upper side in FIG. 10) to the opposite side (lower side in FIG. 10). Stacked and configured.

  Also, on the back surface of the cover film 11, a print R (character “Taro Nagoya” in this example) corresponding to the print data input by the operator via the operation unit 402 of the operation terminal 400 is mirror image printed. It is printed.

  Next, the control contents executed by the control circuit 40 of the label producing apparatus 100 will be described with reference to FIG.

  In FIG. 11, for example, when the operator turns on the power of the label producing apparatus 100, this flow is started ("START" position).

  First, in step S10, the control circuit 40 outputs a control signal to the cartridge sensor 37, detects the type of the cartridge 10 or the like mounted on the cartridge holder 27 (in other words, the type of roll), and the detection result is stored in, for example, the RAM 48. To remember. At this time, if no cartridge is mounted, information to that effect is detected. The control circuit 40 may constantly input the detection result of the cartridge sensor 37 and store it in the RAM 48 at this timing. As described above, the type of the cartridge 10 in this embodiment includes a laminate type, a heat sensitive type, and a receptor type.

  In step S20, the control circuit 40 determines whether the creation instruction signal output from the operation terminal 400 is input via the communication line NW. The determination is not satisfied until the creation instruction signal is input from the operation terminal 400, the loop is waited, and if the creation instruction signal is input from the operation terminal 400, the determination is satisfied and the print data included in the creation instruction signal is stored in the text memory. The data is stored in 48A and the process proceeds to step S30.

  In step S30, the control circuit 40 reads the printing data stored in the text memory 48A in step S20 and performs, for example, predetermined conversion, and dot pattern data (= print driving) corresponding to the printing content on the cover film 11 or the like. Data). Then, it is stored in the print buffer 48B.

  Thereafter, in step S100, the control circuit 40 executes a label creation process (see FIG. 12 described later for the detailed procedure) for creating a print label LB1 on which a desired print has been performed.

  In step S40, the control circuit 40 accesses the table storage unit 49 and refers to a parameter table (see FIG. 13 to be described later) representing parameter information for calculating the remaining tape amount for each type of the cartridge 10 or the like. . Then, parameter information corresponding to the type of cartridge detected in step S10 is acquired from the parameter table. This parameter information includes the tape thickness t of the label producing tapes 16, 16 ', 16 "and the inner peripheral diameter d of the tape rolls 17, 17', 17". An example of the parameter table stored in the table storage unit 49 is shown in FIG.

  As shown in FIG. 13, in the parameter table, the tape thickness t (mm), the total length M (mm), the roll inner peripheral diameter d (mm), and the roll outer peripheral diameter D (mm) are stored in advance for each type of cartridge. It is registered. The full length M and the roll outer diameter D here are values (initial values) Mo and Do when the cartridge is not used. Among these, the tape thickness t and the roll inner peripheral diameter d are acquired by the control circuit 40 in step S40 as parameter information for calculating the remaining tape amount.

  That is, according to the example of FIG. 13, in step S40, if the cartridge detected in step S10 is a laminate type, t = 0.120 (mm), Mo = 8000 (mm), d = 17. (Mm), Do = 39.0 (mm) content parameter information is acquired. If the cartridge detected in step S10 is a receptor type, t = 0.090 (mm), Mo = 8000 (mm), d = 17 (mm), Do = 34.7 (mm). Content parameter information is acquired. If the cartridge detected in step S10 is a thermal type, t = 0.160 (mm), Mo = 4000 (mm), d = 22 (mm), Do = 36.0 (mm). Content parameter information is acquired.

  Returning to FIG. 11, after that, in step S50, the control circuit 40 calculates the remaining tape amount. Here, the remaining amount of tape means the remaining length of the base tape 16 in the base tape roll 17 when the cartridge mounted on the cartridge holder 27 is a laminate type cartridge 10, and the heat sensitive cartridge 10 '. Is the remaining length of the thermal tape 16 'in the thermal tape roll 17', and in the case of the receptor type cartridge 10 ", it is the remaining length of the receptor tape 16" in the receptor tape roll 17 ". In the laminate type cartridge 10, the base tape 16 uses the tape length of the base tape 16 in the base tape roll 17 instead of the cover film 11 in the cover film roll 12 as the base tape 16. The total length is 0 so that the remaining amount of tape is 0 before the cover film 11 This is because has been set in order.

  In each cartridge 10, 10 ', 10 ", the tape rolls 17, 17', 17" rotate the spools 17a, 17a ', 17a "about the spools 17a, 17a', 17" to feed the label producing tapes 16, 16 ', 16 ". However, since the outer peripheral diameter of the tape rolls 17, 17 ', 17 "is gradually reduced as the label forming tapes 16, 16', 16" are fed out, the tape is fed when the tape transport speed is constant. The angular velocities around the spools of the rolls 17, 17 ′, 17 ″ gradually increase as the roll outer diameter decreases. Thus, there is a predetermined correlation between the roll outer diameter and the tape roll angular speed. As described above, since the roll outer peripheral diameter and the remaining tape amount correspond to each other on a one-to-one basis, in the present embodiment, the correlation is used to determine the detection result of the first optical sensor 51. Tape roll 17, 17 ', and calculates the residual tape amount from the angular velocity of 17 "(see step S155 of FIG. 12 described later).

  Next, details of the method for calculating the remaining tape amount will be described with reference to FIGS.

  In general, the side area of a roll formed by winding a tape can be equated with the side area of all tapes fed out from the roll. The side area of the tape is a value obtained by multiplying the total length M of the tape by the tape thickness t. On the other hand, the side area of the roll can be obtained by subtracting the area of the inner circumference circle obtained from the roll inner circumference diameter d from the area of the outer circumference circle obtained from the roll outer circumference diameter D as shown in FIG. .

Therefore, as shown in FIG. 14B, an equation is established that the side area of the tape is equal to the area obtained by subtracting the area of the inner circumferential circle from the area of the outer circumferential circle. That is, since the left side is the side area of the tape, t (tape thickness) × M (tape length), and the right side is the area obtained by subtracting the area of the inner circumferential circle from the area of the outer circumferential circle, so that π (D / 2) ² −π (d / 2) ² . Rearranging this leads to M = π (D ² −d ² ) / 4t. Hereinafter, this formula is referred to as “Formula 1”.

  Among the variables of the above “Equation 1”, the tape thickness t and the inner diameter d of the roll are acquired from the parameter table as described above. Therefore, if the roll outer peripheral diameter D is obtained, the total tape length M as the remaining tape amount (hereinafter referred to as “tape remaining amount M” as appropriate) can be calculated.

  Here, as shown in FIG. 15A, when the angular velocity of the roll is ω (rad / s) and the transport speed of the tape fed out from the roll is S (mm / s), it is shown in FIG. Thus, the conveyance speed S is expressed by D (roll outer diameter) / 2 × angular velocity ω. From this equation, D = 2S / ω is derived. Hereinafter, this formula is referred to as “Formula 2”. Here, the transport speed S is determined based on the specifications of the label producing apparatus 100 and the cartridge 10 (that is, the rotation speed of the tape feed motor 33 and the diameter of the tape feed roller 18), and is stored in advance in the RAM 48, for example. Yes. Further, the angular velocity ω (rad / s) is a pulse output from the first optical sensor 51 as an angle θ (rad) corresponding to one of the plurality of detectors 75 provided on the detection object 74. The value divided by the period E (s). That is, ω = θ / E. Hereinafter, this equation is referred to as “Equation 3”. In the present embodiment, as described above, 48 detectors 75 are formed on the detection object 74, so the angle θ is 2π / 48 = π / 24 (rad). This angle θ is also stored in advance in the RAM 48 or the like.

  Therefore, the control circuit 40 detects the angular velocity ω of the roll by the above “Expression 3” based on the pulse period E output from the first optical sensor 51 and the angle θ read from the RAM 48. The roll outer diameter D is calculated from the angular velocity ω and the conveyance speed S read from the RAM 48 based on the “Expression 2”. The remaining tape amount M can be calculated from the calculated roll outer peripheral diameter D, the tape thickness t and the roll inner peripheral diameter d acquired from the parameter table, based on the above “Equation 1”.

  Returning to FIG. 11, after that, in step S60, the control circuit 40 outputs the tape remaining amount information corresponding to the calculated tape remaining amount M to the operation terminal 400 via the communication line NW. As a result, the remaining tape amount M is displayed on the display unit 401 of the operation terminal 400. Then, this flow ends.

  Note that the tape remaining amount display on the operation terminal 400 may be a numerical value, or may be displayed using a figure such as a bar graph or other symbols, for example. Moreover, when displaying by a numerical value, you may display finely by a millimeter unit or a centimeter unit, and may display roughly by a meter unit.

  In FIG. 11 described above, step S40 functions as the parameter information acquisition unit described in the claims, step S50 functions as the remaining amount specifying unit, and step S60 functions as the remaining amount related information output unit. To do. The tape remaining amount information output in step S60 corresponds to remaining amount related information.

  The detailed procedure of step S100 in FIG. 11 will be described with reference to FIG. In FIG. 12, a case where the print label LB1 is produced using the laminate type cartridge 10 will be described as an example.

  First, in step S110, the control circuit 40 outputs a control signal to the tape feed motor drive circuit 34, and the tape feed motor 33 drives the tape feed roller drive shaft 30 and the ribbon take-up roller drive shaft 31. Thereby, the feeding of the base tape 16 from the base tape roll 17 and the feeding of the cover film 11 from the cover film roll 12 are started, and the base tape 16, the cover film 11, and the label tape for printing are started. 23 (hereinafter simply referred to as “base tape 16 or the like”) is started.

  Thereafter, in step S120, the control circuit 40 determines whether or not the base tape 16 or the like has been conveyed by a predetermined amount. The predetermined amount is, for example, a conveyance distance that the front end of the print area provided in the cover film 11 reaches a position where the print head 19 is substantially opposed. This conveyance distance determination may be performed, for example, by detecting a marking provided on the base tape 16 with a known tape sensor (not shown). The determination is not satisfied until the predetermined amount is conveyed, and the loop waits. If the predetermined amount is conveyed, the determination is satisfied and the process proceeds to step S130.

  In step S <b> 130, the control circuit 40 outputs a control signal to the print head drive circuit 32 and causes the print head 19 to start printing corresponding to the print drive data in the print area of the cover film 11.

  In step S140, the control circuit 40 determines whether or not printing for the print area of the cover film 11 has been completed. The determination is not satisfied until all the printing is completed, and the loop waits. When all the printing is completed, the determination is satisfied, and the process proceeds to step S150.

  In step S150, the control circuit 40 determines whether the base tape 16 or the like has been further conveyed by a predetermined amount. The predetermined amount is, for example, a conveyance distance that the entire printing area exceeds the cutter 28 by a predetermined length. For example, the conveyance distance determination at this time may be the same as in step S120. The determination is not satisfied until the predetermined amount is conveyed, and the loop waits. If the predetermined amount is conveyed, the determination is satisfied and the process proceeds to step S155.

  In step S155, the control circuit 40 determines the timing of the pulse train, which is the detection result of the detector 75 formed on the detected body 74 by the first optical sensor 51, when the tape transport speed after starting printing is constant. Input in parallel with the transport operation, and the angular velocity of the base tape roll 17 is detected based on the pulse period.

  In step S160, the control circuit 40 outputs a control signal to the tape feed motor drive circuit 34, stops the drive of the tape feed roller drive shaft 30 and the ribbon take-up roller drive shaft 31 by the tape feed motor 33, and the base tape The feeding of the base tape 16 and the cover film 11 from the roll 17 and the cover film roll 12 and the transport of the base tape 16 and the like are stopped.

  Thereafter, in step S170, the control circuit 40 determines whether or not the cutter driving button 38 has been manually operated by the operator. The determination is not satisfied until the cutter driving button 38 is manually operated, loops and waits, and when the cutter driving button 38 is manually operated, the determination is satisfied and the routine goes to Step S180.

  In step S180, the control circuit 40 outputs a control signal to the solenoid drive circuit 36, drives the solenoid 35, and cuts the printed label tape 23 by the cutter 28. As described above, at this time, all of the printed label tape 23 including the printing area has sufficiently exceeded the cutter 28, and the printing corresponding to the print drive data is performed by cutting the cutter 28. A label LB1 is generated.

  Thereafter, in step S190, the control circuit 40 outputs a control signal to a discharge motor (not shown) for driving a separately provided discharge roller (not shown), and the label is generated in step S180. The print label LB1 is discharged out of the apparatus. If the print label LB1 can be discharged out of the apparatus by manual operation without a discharge motor, step S190 may be omitted. Thereafter, this routine is terminated.

  As described above, in the label creation process, the angular velocity of the base tape roll 17 is detected immediately before printing is completed and the transport of the base tape 16 or the like is stopped. The remaining amount of tape can be detected with high accuracy.

  In the first embodiment described above, the cartridge sensor 37 acquires the type information of the cartridge 10 or the like attached to the cartridge holder 27. Further, a detected body 74 that rotates at the same angular velocity as the tape rolls 17, 17 ', and 17 "is provided in the cartridge casing 70, and the first optical sensor 51 places the detector 75 of the detected body 74 in the cartridge casing. Optically detected from the outside of the body 70. Then, the control circuit 40, based on the type information acquired by the cartridge sensor 37 and the detection result of the first optical sensor 51 in step S50, the tape rolls 17, 17 '. , 17 ″ and the remaining tape amount information corresponding to the calculated remaining tape amount is output to the operation terminal 400 in step S60. Accordingly, the remaining tape amount M can be displayed on the display unit 401 of the operation terminal 400.

  In this way, by calculating the remaining tape amount M based on the type information of the cartridge 10 and the like and the detection result of the first optical sensor 51, the plurality of different types of cartridges 10, 10 ′ described above in the label producing apparatus 100 are obtained. , 10 ″, the remaining tape amount M can be calculated in accordance with the type of cartridge. As a result, even when the operator creates a plurality of different types of print labels LB1, the remaining tape amount can be calculated. The amount M can be reliably recognized.

  In the present embodiment, in particular, the control circuit 40 acquires parameter information related to the tape rolls 17, 17 ′, 17 ″ based on the type information such as the cartridge 10 acquired by the cartridge sensor 37 in step S 40. In step S50, using the parameter information acquired in step S40 and the angular velocity ω of the tape rolls 17, 17 ′, 17 ″ based on the detection result of the first optical sensor 51, “expression 1” and “expression 2”. The remaining tape amount M is calculated based on “Formula 3”. Thus, by sequentially calculating the remaining tape amount M based on the parameter information and the detection result of the first optical sensor 51, for example, compared to the case where the remaining tape amount M is specified using a previously prepared remaining amount table. The remaining amount of tape M can be detected with high accuracy without the accuracy being affected by the amount of data in the table. As a result, the operator can grasp the remaining tape amount M in detail. In addition, since the remaining amount of tape M can be detected with high accuracy, the print label LB1 is continuously produced according to the remaining amount of tape M, or the conveyance force (tape feeding) by the tape feed roller 18 according to the remaining amount of tape M. It is possible to perform processing using the remaining amount of tape, such as controlling the force) to stabilize tape conveyance.

  In this embodiment, in particular, when the type of cartridge is different, parameter information such as the tape thickness of the label producing tape 16, 16 ', 16 "and the inner peripheral diameter of the tape rolls 17, 17', 17" is different. Correspondingly, the tape thickness t of the label producing tapes 16, 16 ', 16 "and the inner peripheral diameter d of the tape rolls 17, 17', 17" are previously stored in the table storage unit 49 for each type of cartridge 10 or the like. The parameter table to represent is stored. Then, the control circuit 40 refers to the parameter table in step S40, and the tape thickness t corresponding to the type information such as the cartridge 10 acquired by the cartridge sensor 37 and the inner peripheral diameter d of the tape rolls 17, 17 ′, 17 ″ are obtained. In step S50, the remaining tape amount M is calculated using the parameter information and the angular velocities ω of the tape rolls 17, 17 ′, 17 ″. As described above, the tape thickness t and the inner peripheral diameter d of the tape rolls 17, 17 ′, and 17 ″ that are different for each type of the cartridge 10 and the like are obtained as parameter information, and the remaining tape M is calculated. It is possible to reliably specify the remaining tape amount M corresponding to a type such as the tape thickness t and the inner peripheral diameter d of the tape rolls 17, 17 ′, 17 ″ using the parameter table prepared in advance. Thus, the amount of information to be acquired can be reduced as compared with the case where the cartridge sensor 37 acquires the tape thickness t and the inner peripheral diameter d of the tape rolls 17, 17 ', 17 "in addition to the cartridge type information. Therefore, the structure of the cartridge sensor 37 which is a mechanical sensor mechanism can be simplified.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order.

(1-1) When the first optical sensor is a transmissive sensor In the first embodiment, a reflective sensor is used as the first optical sensor 51. However, a transmissive sensor may be used. The configuration in the vicinity of the cartridge when the transmissive first optical sensor 51 'is used will be described with reference to FIG.

  In FIG. 16, the first optical sensor 51 ′ of this modification has a light emitting part 51 a ′ and a light receiving part 51 b ′, and receives the detection light output from the light emitting part 51 a ′ and transmitted through the detection object 73. This is a transmissive optical sensor detected by 51b '. The light emitting portion 51a ′ is provided inside the opening / closing lid 102, and the light receiving portion 51b ′ is provided on the bottom surface 27b of the cartridge holder 27. When the opening / closing lid 102 is closed, the light emitting portion 51a ′ and the light receiving portion 51b ′ are The cartridge 10 and the like mounted on the cartridge holder 27 are opposed to each other at corresponding positions on one side and the other side. At this time, the detector 75 of the detection object 73 includes a transparent or translucent light-transmitting region 75c (not shown) and a light shielding region 75s (not shown).

  Two transmission holes 72A ′ and 72B ′ for transmitting the detection light from the first optical sensor 51 ′ are provided at corresponding positions of the upper portion 70u and the lower portion 70d of the cartridge housing 70, respectively. In this modification, the detector 75 is formed on any of the film members 73 and 74 provided so as to be in contact with both ends of the tape rolls 17, 17 ′ and 17 ″ in the width direction (vertical direction in FIG. 16). However, in the example shown in Fig. 16, the detector 75 is formed on the upper film member 73 when the cartridge 10 or the like is attached to the cartridge holder 27. Therefore, in this modification, the film member 73 is formed. Is appropriately referred to as “detected body 73”.

  The configuration other than the above is the same as that of the above-described embodiment. In the present modification, the first optical sensor 51 'corresponds to the optical detection means described in the claims.

  According to this modification, since the transmissive first optical sensor 51 ′ is used, the sensor support mechanism 60 that supports the sensor so as to be able to advance and retreat relative to the cartridge holder 27 as in the case of using the reflective first optical sensor 51. There is no need to provide. Therefore, the structure of the label producing apparatus 100 can be simplified. In addition, since both the film members 73 and 74 can be configured as the detection target, the degree of freedom is improved. Further, as shown in FIG. 16, even when the upper film member 73 is the detected object 73, the detected object 73 is composed of a transparent or translucent film member, so that the operator can check the remaining amount. Through the window 71, the tape rolls 17, 17 ', and 17 "can be seen through the detected object 73, and the rough remaining amount of the tape can be visually confirmed. At this time, the detector 75 is detected. Since it is provided at the outer peripheral side end of the body 73, the detector 75 does not get in the way when visually recognizing the remaining tape amount.

(1-2) When a warning is issued when the remaining tape amount is low, a warning may be issued when the remaining tape amount falls below a preset lower limit value. The contents of control executed by the control circuit 40 in this modification will be described with reference to FIG.

  In FIG. 17, steps S10 to S50 are the same as those in FIG. In the next step S55, the control circuit 40 determines whether or not the remaining tape amount calculated in the above-described step S50 is less than or equal to the lower limit value. This lower limit value is a predetermined value as the remaining tape amount to be warned to the operator, and is stored in advance in the RAM 48, for example. If the remaining tape amount is less than or equal to the lower limit value, the determination is satisfied, and the routine goes to Step S57.

  In step S57, the control circuit 40 outputs tape remaining amount information corresponding to the calculated tape remaining amount and predetermined warning information indicating that the tape remaining amount is low to the operation terminal 400 via the communication line NW. To do. As a result, a warning is displayed together with the remaining tape amount on the display unit 401 of the operation terminal 400. Then, this flow ends.

  On the other hand, if the remaining tape amount is larger than the lower limit in step S55, the determination is not satisfied, and the routine goes to step S60. Step S60 is the same as FIG. 11 described above, and the tape remaining amount information is output to the operation terminal 400 via the communication line NW. As a result, the remaining tape amount is displayed on the display unit 401 of the operation terminal 400. Then, this flow ends.

  In the present modification, steps S57 and S60 function as remaining amount related information output means. The warning information output in step S57 and the remaining tape information output in step S60 correspond to remaining amount related information.

  According to the above modification, an alarm is given to the operator when the remaining tape amount is less than a predetermined value, so that the device malfunctions when the operator performs printing without a tape without noticing the tape end. Can be prevented.

  In the above modification, only the lower limit value is set as the threshold value. However, a plurality of threshold values that are set in advance are set, and each time the remaining level information corresponding to each threshold value is manipulated, the threshold value is manipulated. You may output to the terminal 400, respectively. As a result, as the remaining tape amount gradually decreases, the remaining tape amount is notified to the operator step by step, for example, by displaying characters such as “many”, “medium”, and “low”, and graphic / symbols such as bar graphs. can do.

(1-3) In the case of having a remaining amount table In the above embodiment, the control circuit 40 determines the angular velocity ω based on the detection result of the first optical sensor 51, the tape thickness t and the roll inner peripheral diameter d acquired from the parameter table. Based on the above, the remaining tape amount M is calculated using the above-mentioned “Expression 1”, “Expression 2”, and “Expression 3”. However, the remaining tape amount M is calculated in advance, and the angular velocity ω and the remaining tape amount are calculated. A remaining amount table that represents the correlation with M for each type of cartridge may be stored in the table storage unit 49.

  An example of the remaining amount table stored in the table storage unit 49 will be described with reference to FIG. In the example shown in FIG. 18, in the remaining amount table, every time the pulse period E output from the first optical sensor 51 changes by 0.005 (s), the corresponding angular velocity ω (rad / s), the roll outer periphery The diameter D (mm) and the remaining tape amount M (mm) for each cartridge type are calculated and registered. Here, the conveyance speed S is set to 10 (mm / s), the angle θ is set to π / 24 (rad), and the values of the respective parameters shown in FIG. The tape remaining amount M is calculated by “Expression 3”. The step of the pulse period E may be a finer value or a larger value.

  The contents of control executed by the control circuit 40 in this modification will be described with reference to FIG. In FIG. 19, steps S10 to S100 are the same as those in FIG. In step S50A instead of the next step S50, the control circuit 40 selects a portion corresponding to the cartridge type (in other words, roll type) detected in step S10 described above in the remaining amount table stored in the table storage unit 49. The tape remaining amount M corresponding to the pulse period E based on the detection result of the first optical sensor 51 or the angular velocity ω of the tape rolls 17, 17 ′, 17 ″ (see step S 155 in FIG. 12) is specified. Step S60 is the same as that in FIG.

  Specifically, for example, when a laminate type cartridge 10 is mounted and the pulse period E is 0.220 (s), the remaining tape amount M is 5508 (mm) as shown in FIG. Become. Therefore, the remaining tape amount M is displayed as 5508 (mm) when the pulse period E reaches 0.220 (s), and then the remaining tape amount until the pulse period E reaches the next 0.215 (s). M is displayed as 5508 (mm). When the pulse period E reaches the next 0.215 (s), the remaining tape display is changed to 5176 (mm). In this manner, the remaining tape amount is displayed every time the pulse period E changes by 0.005 (s).

  In this modification, the step S50A functions as remaining amount specifying means described in the claims. The table storage unit 49 corresponds to a first storage unit.

  According to this modification, by specifying the remaining tape amount M using a remaining amount table prepared in advance, the remaining tape amount M is sequentially determined based on the detection result of the first optical sensor 51 as in the above embodiment. Compared with the case of calculation, since the calculation is not necessary, it is possible to simplify the control content relating to the remaining tape amount detection. As a result, the CPU and the like can be made low specification and cost can be reduced. In addition, there is an effect that the time required for specifying the remaining amount of tape can be shortened by the amount that calculation is not required.

  In the above description, the remaining amount table is set finely. However, for example, as shown in FIG. 20, a more roughly set table may be used. In the example shown in FIG. 20, the pulse period is calculated and registered every time the remaining tape amount changes by 1 (m). In this case, for example, when the pulse period E is detected as 0.200 (s), the tape is set as “4 to 5 m” for the laminate type, “5 to 6 m” for the receptor type, and “2 to 3 m” for the heat sensitive type. The remaining amount may be displayed.

(1-4) Others In the above description, the display unit 401 of the operation terminal 400 that is a separate body from the label producing apparatus 100 is used as a display unit for displaying the remaining tape amount. It is good also as a structure which provides the display part integrally in the label production apparatus 100, and uses this as a display means.

  In the above description, the case where the printed label tape 23 after printing is cut with the cutter 28 to create the print label LB1 has been described as an example. However, the present invention is not limited to this. That is, in the case where a label mount (so-called die-cut label) previously separated into a predetermined size corresponding to the label is continuously arranged on the tape fed out from the roll, even if it is not cut by the cutter 28, After the tape has been discharged from the tape discharge port 104, only the label mount (the one on which the corresponding printing has been performed) may be peeled off from the tape to produce the print label LB1. Applicable.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The present embodiment is an embodiment of a label producing apparatus capable of producing a print label using a plurality of different types of tape rolls without using a cartridge.

  As shown in FIG. 21, the label producing apparatus 201 includes a main body housing 202, a transparent resin upper cover 205, and a transparent resin made upright so as to face the substantially central portion on the front side of the upper cover 205. The tray 206 includes a power button 207 disposed on the front side of the tray 206, a cutter lever 209, and the like.

  As shown in FIG. 22, a roll mounting mechanism 203 is housed and disposed in a roll housing section 204 that functions as a roll holder. The roll mounting mechanism 203 includes a positioning and holding member 212 and a guide member 220, and a tape 203 A (label producing tape) having a predetermined width is wound around in a roll shape so as to constitute a tape roll 300. Yes. That is, the guide member 220 as one side wall and the positioning and holding member 212 as the other side wall are provided on both sides in the axial direction of the tape 203A so as to be substantially orthogonal to the axis. In addition, the upper cover 205 is attached to the upper edge of the rear side so as to be openable and closable so as to cover the upper side of the roll storage unit 204.

  In addition, a support member 215 is provided at one side edge in a direction substantially perpendicular to the transport direction of the roll storage unit 204, and the support member 215 has a substantially vertically long U-shape as viewed from the front. One positioning groove 216 is formed. A mounting member 213 that protrudes outward from the positioning holding member 212 and has a vertically long cross-sectional shape that is narrow in the downward direction when viewed from the front is narrow in the downward direction. The support member 215 is fitted into the first positioning groove 216 by being in close contact therewith. The protruding height dimension of the mounting member 213 is formed to be substantially equal to the width dimension of the first positioning groove 216.

  A lever 227 is provided at the transport direction front end of the other side edge of the roll storage unit 204.

  As shown in FIG. 23, the tape 203A has a three-layer structure in this example (see a partially enlarged view), and is on the opposite side (lower right side in FIG. 23) from the side wound outward (upper left side in FIG. 23). ) In the order of release paper 203a, adhesive layer 203b, and long thermal paper (so-called thermal paper) 203c having self-coloring properties.

  The release paper 203a is bonded to the thermal paper 203c by the adhesive layer 203b on the back side of the thermal paper 203c (upper left side in FIG. 23). The release paper 203a is configured such that when the finally completed print label LB2 is affixed to a predetermined product or the like, it can be adhered to the product or the like by the adhesive layer 203b by peeling it off.

  A power cord 210 is connected to one side end of the back surface of the main body housing 202.

  In addition, an annular film member is disposed on both ends of the tape roll 300 in the axial direction (perpendicular to the paper surface in FIG. 23) so as to come into contact with both ends of the tape roll 300 in the width direction (perpendicular to the paper surface in FIG. 23). 273 (not shown) and a film member 274 are provided. Of these, the film member 274 (see FIG. 23) on the right side when viewed from the front of the apparatus when the tape roll 300 is mounted has a light-reflective region 275w and light absorption at the outer peripheral side end in the radial direction. A plurality of detectors 275 configured with the sex region 275 b are formed at predetermined intervals in the circumferential direction of the tape roll 300. As shown in the figure, 16 detectors 275 are formed in this embodiment, but other numbers may be used. The film member 274 is provided, for example, on the side surface of the tape roll 300 so as to rotate at an angular velocity (in this example, the same angular velocity) interlocked with the tape roll 300 attached to the roll storage unit 204. In this specification, the film member 274 is appropriately referred to as a “detected body 274”. In addition, in order to prevent the illustration from becoming complicated, the illustration of the film member is omitted in the drawings other than FIGS.

  The detected body 274 is made of a transparent or translucent film material, like the detected body 74 of the first embodiment. The light reflective region 275w constituting the detector 275 is formed by printing white or silver on the film and reflects incident light. The light-absorbing region 275b is formed transparent or semi-transparent by printing black on the film or by not printing or the like, and absorbs or transmits incident light.

  An optical sensor 251 is provided at the rear end in the transport direction on one side substantially perpendicular to the transport direction of the roll storage unit 204. The optical sensor 251 is an optical sensor that optically detects the detector 275 from the outside of the roll, like the first optical sensor 51 of the first embodiment. That is, similar to the first optical sensor 51, the optical sensor 251 has a light emitting unit (not shown) and a light receiving unit (not shown), and is detected from the light emitting unit and reflected by the detected object 274. It is a reflective sensor that detects light with a light receiving unit. A control circuit 410 (see FIG. 28 described later) described later can detect the angular velocity of the tape roll 300 based on the pulse output from the optical sensor 251.

  Similar to the detector 75 of the first embodiment, the detector 275 has a radially outer peripheral end of the detected body 274, specifically, the contour of the roll in the state where the outer diameter of the tape roll 300 is the largest. (In FIG. 23, for the sake of clarification of the configuration, the detector 275 is exaggerated so as to be present on the inner peripheral side of the roll contour. ing). As a result, since the outer diameter of the tape roll 300 thereafter only becomes smaller as the tape 203A is fed out, the detector 275 and the contour of the roll do not overlap, and the detection of the detector 275 by the optical sensor 251 is good. Can be done.

  As shown in FIG. 24, the tape 203A is wound around a winding core (reel member) 203B in a roll shape to constitute the tape roll 300.

  Between the positioning holding member 212 and the guide member 220, a substantially cylindrical shaft member 240 is provided so as to be arranged in the axial direction on the inner peripheral side of the winding core 203B. The member 212, the guide member 220, and the shaft member 240 constitute a roll mounting mechanism 203. The shaft member 240 is provided with a plurality of types (for example, four types) of length dimensions corresponding to the length dimensions of the core 203B described above, and the length dimension of the shaft member 240 is changed. As a result, a plurality of types of roll mounting mechanisms 203 on which tape rolls 300 having tapes 203A having different widths (however, the outer diameters d of the cores 203B are all the same) can be mounted. Note that the maximum winding length of the tape 203A wound around the roll mounting mechanism 203 is, for example, about 30 m.

  An engagement recess 215A is formed at the inner base end of the support member 215, and an elastic locking piece 212A protruding from the lower end of the positioning holding member 212 is engaged with the engagement recess 215A. Yes.

  On the bottom surface of the roll storage portion 204, a positioning recess 204A having a horizontally long rectangular shape in a plan view with a predetermined depth (for example, about 1.5 to 3 mm) from the inner base end portion of the support member 215 substantially perpendicular to the transport direction.

It is configured to be fitted into any one of the second positioning groove portions 222A to 222D (see FIG. 27 described above).

  Further, the lower end portion of the mounting member 213 of the positioning holding member 212 of the roll mounting mechanism 203 has a predetermined length in the lateral direction from the lower end portion of the mounting member 213 (in this example, about 1.5 mm to A guide portion 257 having a substantially rectangular flat plate shape (in this example, a length of about 1.5 mm to 3 mm) is formed. Accordingly, when the roll mounting mechanism 203 is mounted, the mounting member 213 is inserted into the first positioning groove 216 while the guide portion 257 formed at the lower end of the mounting member 213 is brought into contact with the outer end surface of the support member 215. By doing so, the roll mounting mechanism 203 can be mounted while being easily positioned.

  The lower end edge portion of the extending portion 256 of the positioning holding member 212 is extended so as to protrude downward by a predetermined length (in this example, about 1 mm to 2.5 mm) from the lower end edge portion of the guide member 220. The detected portion 260 having a substantially rectangular shape that extends a predetermined length in a substantially perpendicular inner direction is formed at the lower edge.

  The detected portion 260 is formed with sensor holes 260A to 260D arranged in a substantially L shape at predetermined positions facing the roll detection sensors S1 to S4 described above, and cooperates with the sensors S1 to S4. Thus, the type of the tape roll 300 is specified.

  An example of the mounting behavior of the roll mounting mechanism 203 configured as described above to the label producing apparatus 201 will be described with reference to FIGS. 30 (A) and 30 (B).

  FIG. 30A shows an example in which the tape roll 300 around which the maximum width tape 203A is wound is mounted on the winding core 203B. In FIG. 30A, first, the attachment member 213 of the positioning holding member 212 of the roll mounting mechanism 203 is inserted into the positioning groove 216 of the support member 215. Then, the lower end surface of the third extending portion 244 of the guide member 220 of the roll mounting mechanism 203 is brought into contact with the mounting portion 221, and the fourth extending portion 245 of the guide member 220 is transported to the mounting portion 221. It is made to fit in the 2nd positioning groove part 21A formed in a direction rear side corner | angular part. Further, the lower end edge portion of the first extension portion 242 of the guide member 220 is fitted and brought into contact with a positioning recess portion 204 </ b> A formed on the bottom surface portion of the roll storage portion 204.

  At the same time, the detected portion 260 formed at the lower end portion of the extending portion 256 of the positioning holding member 212 of the roll mounting mechanism 203 is inserted into the detection recess 204B formed inside the base end portion of the support member 215. The elastic locking piece 212 </ b> A is engaged with the engagement recess 215 </ b> A formed at the base end portion of the support member 215.

  Subsequently, in a state where the lever 227 is rotated upward, the tape 203A is pulled out while bringing one side edge of the tape 203A into contact with the inner surface of the guide member 220, and the other side of the tape 203A. The end edge portion is inserted into the insertion port 218 while being brought into contact with the guide rib portion 223 erected on the side edge portion of the insertion port 218. Thereafter, by rotating the lever 227 downward, the leading end of the tape 203A is pressed against the platen roller 226 by the thermal head 231, and printing is possible.

  FIG. 30B shows an example in which the tape roll 300 around which the tape 203A having the minimum width is wound is mounted on the winding core 203B. In FIG. 30B, first, the attachment member 213 of the positioning holding member 212 of the roll mounting mechanism 203 is inserted into the positioning groove 216 of the support member 215. Then, the lower end surface of the third extending portion 244 of the guide member 220 of the roll mounting mechanism 203 is brought into contact with the mounting portion 221, and the fourth extending portion 245 of the guide member 220 is transported to the mounting portion 221. It is made to fit in 2nd positioning groove part 221D formed in a direction back side corner | angular part. Further, the lower end edge portion of the first extension portion 242 of the guide member 220 is fitted and brought into contact with a positioning recess portion 204 </ b> A formed on the bottom surface portion of the roll storage portion 204.

  At the same time, the detected portion 260 formed at the lower end portion of the extending portion 256 of the positioning holding member 212 of the roll mounting mechanism 203 is inserted into the detection recess 204B formed inside the base end portion of the support member 215. The elastic locking piece 212 </ b> A is engaged with the engagement recess 215 </ b> A formed at the base end portion of the support member 215.

  Through the above operation, the roll mounting mechanism 203 is detachably attached to the roll storage unit 204, and the presence or absence of the sensor holes 260A to 60E of the detected portion 260 facing each other can be detected via the roll detection sensors S1 to S5. It becomes.

  Thereafter, the lever 227 is pivoted upward and the like is the same as described above, and a description thereof will be omitted.

  The print label LB2 formed after the cutting of the tape 203A as described above has the above-described three-layer structure, as shown in FIGS. 31 (a), 31 (b), and 32. From the surface side (upper side in FIG. 32) to the opposite side (lower side in FIG. 32), thermal paper 203c, adhesive layer 203b, and release paper 203a are laminated in this order. As described above, the print R (in this example, “AA-AA” characters) is printed on the surface of the thermal paper 203c.

  In the present embodiment, as described above, different types of tape rolls are selectively used by selectively mounting the roll mounting mechanism 203 on which different types of tape rolls 300 are mounted on the roll storage unit 204. Thus, the print label LB2 can be created. At that time, similarly to the first embodiment, the type of the mounted tape roll 300 can be detected, and the remaining tape amount M can be calculated according to the type. Hereinafter, the contents will be described in order.

  The contents of control executed by the control circuit 410 of the label producing apparatus 201 will be described with reference to FIG. FIG. 33 is a diagram corresponding to FIG. 11 of the eleventh embodiment.

  In FIG. 33, for example, when the operator turns on the power of the label producing apparatus 201, this flow is started ("START" position).

  First, in step S210, the control circuit 410 outputs a control signal to the roll detection sensors S1 to S4, detects the type of the tape roll 300 mounted on the roll mounting mechanism 203, and the detection result is stored in the RAM of the control circuit 410. To remember. At this time, if the roll mounting mechanism 203 is not mounted, information to that effect is detected. Note that the control circuit 410 may constantly input the detection results of the roll detection sensors S1 to S4 and store them in the RAM or the like at this timing.

  In step S220, the control circuit 410 receives a creation instruction signal from another terminal, a general-purpose computer, or the like (or from an appropriate operation means provided in the label creating apparatus 201) via the communication circuit 411B. Determine if. Until the creation instruction signal is input, the determination is not satisfied, and the loop waits. When the creation instruction signal is input, the determination is satisfied, the printing data included in the creation instruction signal is stored in an appropriate memory such as the RAM in the control circuit 410, and the process proceeds to step S230.

  In step S230, the control circuit 410 reads the print data stored in the memory in step S220 and performs, for example, predetermined conversion to generate dot pattern data (= print drive data) corresponding to the print contents on the tape 203A. . Then, it is stored in a print buffer (not shown) in the control circuit 410.

  Thereafter, in step S100 ′ (details will be described later) equivalent to step S100 of the first embodiment, the control circuit 410 creates a label producing process for producing a print label LB2 (see FIG. 31 and the like) on which a desired printing is performed. Execute.

  In step S240, the control circuit 410 accesses the table storage unit 410A, and refers to a parameter table (see FIG. 34 described later) representing parameter information for calculating the remaining tape amount for each type of tape roll 300. To do. Then, parameter information corresponding to the type of the tape roll 300 detected in step S210 is acquired from the parameter table. This parameter information includes the tape thickness t of the tape 203A and the inner peripheral diameter d of the tape roll 300. An example of the parameter table stored in the table storage unit 410A is shown in FIG.

  As shown in FIG. 34, the parameter table includes, for each type of tape roll 300, a tape width w (mm), a tape thickness t (mm), a total length M (mm), a tape roll inner peripheral diameter d (mm), And the tape roll outer diameter D (mm) are registered in advance. The full length M and the roll outer diameter D here are values (initial values) Mo and Do when the tape roll 300 is not used. Among these, the tape thickness t and the roll inner peripheral diameter d are acquired by the control circuit 410 in step S240 as parameter information for calculating the remaining tape amount.

  That is, in the example of FIG. 34, in step S240, if the tape 203A wound around the tape roll 300 is a long type, for example, w = 50 (mm), t = 0.18 (mm), Mo Parameter information with contents of = 30000 (mm), d = 30 (mm), and Do = 88.2 (mm) is acquired. When the tape 203A wound around the tape roll 300 is, for example, a middle type, w = 30 (mm), t = 0.20 (mm), Mo = 20000 (mm), d = 30 (mm) , Do = 77.4 (mm) is obtained. When the tape 203A wound around the tape roll 300 is, for example, a short type, w = 10 (mm), t = 0.22 (mm), Mo = 10000 (mm), d = 30 (mm), The parameter information with the content of Do = 60.8 (mm) is acquired.

Returning to FIG. 33, after that, in step S250, the control circuit 410 calculates the remaining tape amount. The method for calculating the remaining tape amount is the same as the method of the first embodiment described with reference to FIGS. 14 and 15, and is calculated using the above-described “Formula 1”, “Formula 2”, and “Formula 3”. . That is,
M = π (D ² −d ² ) / 4t (Equation 1)
D = 2S / ω (2)
ω = θ / E (Equation 3)

  Similar to the first embodiment, the tape thickness t and the roll inner peripheral diameter d are acquired from the parameter table described above. The transport speed S is determined based on the specifications of the label producing apparatus 201 and is stored in advance in the RAM. The angular velocity ω (rad / s) is a pulse period E (s) in which an angle θ (rad) corresponding to one detector 275 among the plurality of detectors 275 provided on the detection target 274 is output from the optical sensor 251. ) Divided by In this embodiment, since the 16 detectors 275 are formed on the detection target 274 as described above, the angle θ is 2π / 16 = π / 8 (rad). This angle θ is also stored in the RAM in advance.

  Therefore, the control circuit 410 detects the angular velocity ω of the roll 300 according to the “Expression 3” based on the pulse period E output from the optical sensor 251 and the angle θ read from the RAM. Then, the outer peripheral diameter D of the roll 300 is calculated from the angular velocity ω and the conveyance speed S read from the RAM based on the “expression 2”. The tape remaining amount M can be calculated from the calculated roll outer peripheral diameter D, the tape thickness t and the roll inner peripheral diameter d acquired from the parameter table, based on the above “Equation 1”.

  Returning to FIG. 33, after that, in step S260, the control circuit 410 outputs the remaining tape amount information corresponding to the calculated remaining tape amount M to another terminal, a general-purpose computer, or the like via the communication circuit 411B. As a result, the remaining tape amount M is displayed on the display unit of the other terminal or general-purpose computer (may be displayed on an appropriate display means provided in the label producing apparatus 201). Then, this flow ends.

  As in the first embodiment, the tape remaining amount display may be performed numerically, or may be displayed using a graphic such as a bar graph or other symbols. Moreover, when displaying by a numerical value, you may display finely by a millimeter unit or a centimeter unit, and may display roughly by a meter unit.

  In FIG. 34 described above, step S240 functions as the parameter information acquisition unit described in the claims, step S250 functions as the remaining amount specifying unit, and step S260 functions as the remaining amount related information output unit. To do. The tape remaining amount information output in step S260 corresponds to remaining amount related information.

  The detailed procedure of step S100 ′ of FIG. 34 is the same as the procedure of step S100 of the first embodiment, and the contents will be described with reference to FIG.

  In FIG. 12, in step S110, the control circuit 410 outputs a control signal to the platen roller circuit 409 (see FIG. 28), and drives the platen roller 226 by the platen roller motor 408 (see FIG. 28). As a result, the feeding and transporting of the tape 203A from the tape roll 300 is started.

  Thereafter, in step S120, the control circuit 410 determines whether or not the tape 203A has been conveyed by a predetermined amount. As in the first embodiment, the predetermined amount is a conveyance distance that, for example, the tip of the print area SA of the tape 203A reaches the position where the thermal head 231 is substantially opposed. Similarly to the above description, the conveyance distance may be determined by detecting the marking provided on the tape 203A with a known sensor (not shown). The determination is not satisfied until the predetermined amount is conveyed, and the loop waits. If the predetermined amount is conveyed, the determination is satisfied and the process proceeds to step S130.

  In step S130, the control circuit 410 outputs a control signal to the print drive circuit 405, and causes the thermal head 231 to start printing corresponding to the print drive data in the print area SA of the tape 203A.

  In step S140, the control circuit 410 determines whether or not printing on the print area SA of the tape 203A has been completed. The determination is not satisfied until all the printing is completed, and the loop waits. When all the printing is completed, the determination is satisfied, and the process proceeds to step S150.

  In step S150, the control circuit 410 determines whether or not the tape 203A has been further conveyed by a predetermined amount. The determination is not satisfied until the predetermined amount is conveyed, and the loop waits. If the predetermined amount is conveyed, the determination is satisfied and the process proceeds to step S155.

  In step S155, the control circuit 410 determines the timing of the pulse train, which is the detection result of the detector 275 formed on the detected body 274 by the optical sensor 251, when the tape transport speed after starting printing is constant. The angular velocity of the tape roll 300 is detected based on the pulse period.

  In step S160, the control circuit 410 outputs a control signal to the platen roller drive circuit 409, stops driving the platen roller 226 by the platen roller motor 408, and stops feeding and transporting the tape 203A from the tape roll 300. . Thus, when the operator manually operates the cutter lever 209, the tape 203A is cut, and the print label LB2 on which printing corresponding to the print drive data is performed is generated and discharged outside the apparatus. In this embodiment, step S170, step S180, and step S190 in FIG. 12 are omitted, and then this routine is terminated.

  In the second embodiment described above, the roll detection sensors S <b> 1 to S <b> 4 acquire the type information of the tape roll 300 mounted on the roll storage unit 204 via the roll mounting mechanism 203. The optical sensor 251 optically detects the detection element 275 of the detection object 274 that rotates at the same angular velocity as the roll 300. In step S250, the control circuit 410 calculates the remaining tape amount M of the tape roll 300 based on the type information acquired by the roll detection sensors S1 to S4 and the detection result of the optical sensor 251, and in step S260, Outputs the remaining tape information corresponding to the calculated remaining tape amount. As a result, the remaining tape amount M can be displayed to the operator.

  In this way, as in the first embodiment, the remaining tape amount M is calculated based on the type information of the tape roll 300 and the detection result of the optical sensor 251. Even when the tape roll 300 is used, the remaining tape amount M can be calculated corresponding to the roll type. As a result, the operator can reliably recognize the remaining tape amount M even when creating a plurality of different types of print labels LB2.

  In this embodiment, in particular, the control circuit 410 acquires parameter information related to the tape roll 300 based on the type information of the tape roll 300 acquired by the roll detection sensors S1 to S4 in step S240. In step S250, using the parameter information acquired in step S240 and the angular velocity ω of the tape roll 300 based on the detection result of the optical sensor 251, the tape is based on “Expression 1”, “Expression 2”, and “Expression 3”. The remaining amount M is calculated. Thus, by sequentially calculating the remaining tape amount M based on the parameter information and the detection result of the optical sensor 251, for example, compared to the case where the remaining tape amount M is specified using a previously prepared remaining amount table, a table is provided. The remaining amount of tape M can be detected with high accuracy without the accuracy being affected by the amount of data. As a result, the operator can grasp the remaining tape amount M in detail.

  In the present embodiment, in particular, a parameter table representing the tape thickness t of the tape 203A and the inner peripheral diameter d of the tape roll 300 for each type of the tape roll 300 is stored in advance in the table storage unit 410A. Then, the control circuit 410 refers to the parameter table in step S240, and sets the tape thickness t corresponding to the type information of the tape roll 300 acquired by the roll sensors S1 to S4 and the inner peripheral diameter d of the tape roll 300 as parameter information. Get as. In step S250, the remaining tape amount M is calculated using the parameter information and the angular velocity ω of the tape roll 300. As described above, by obtaining the tape thickness t and the inner peripheral diameter d of the tape roll 300 that are different for each type of the tape roll 300 as the parameter information and calculating the remaining tape M, it is possible to correspond to the type of the tape roll 300. It is possible to reliably specify the remaining tape remaining amount M. Further, by specifying the tape thickness t and the inner peripheral diameter d of the tape roll 300 using the parameter table prepared in advance as described above, the tape thickness t is added to the tape roll type information by the roll detection sensors S1 to S4. Since the amount of information to be acquired can be reduced as compared with the case of acquiring the inner diameter d of the tape roll 300, the structure of the roll detection sensors S1 to S4 that are mechanical sensor mechanisms can be simplified.

  In the above embodiments and modifications, the case where the detected bodies 74 and 274 are provided in the cartridge 10 or the tape roll 300 has been described as an example. However, the present invention is not limited to this. An object to be detected may be provided on the apparatus housing side.
